Clinical Trial Overview
This clinical trial studied the effects of different in-office tooth bleaching gels on tooth sensitivity, gum irritation, and overall patient satisfaction.
Study Design
160 participants were divided into two groups of 80. Each group used a different bleaching gel:
- Whiteness HP Maxx (acidic, unstable pH)
- Whiteness HP Automixx Plus (neutral, stable pH)
Both gels contained 35% hydrogen peroxide. The Maxx gel was applied in three 15-minute sessions, while the Automixx Plus gel was applied once for 50 minutes. Afterward, participants used a 10% carbamide peroxide gel at home for two weeks.
Key Findings
The trial found that:
- Tooth sensitivity was significantly lower with the neutral pH gel (p < 0.001).
- Both gels achieved similar whitening results (p > 0.37).
- There was no significant difference in gum irritation between the two groups (p > 0.11).
- Participants reported improved aesthetics and social confidence after treatment (p < 0.05).
Conclusion
Using a neutral and stable pH gel for in-office bleaching reduces tooth sensitivity while maintaining effective whitening results. This approach enhances patient comfort and satisfaction.
Practical Implications
For dental clinics and patients, the findings suggest:
- Choose bleaching gels with neutral pH to minimize discomfort.
- Combine in-office and at-home treatments for optimal results.
Next Steps
Clinics should consider:
- Measuring outcomes such as tooth sensitivity and patient satisfaction after using different gels.
- Implementing pilot projects using the recommended gels and tracking results.
- Exploring AI solutions to manage patient experiences and treatment outcomes.
